IMPROVEMENT iN CAR-COUPLlNG PINS.

Specification forming part of Letters Patent No. IQSLSQI, dated April14, 1874; application led February 24, 1874.

To all whom it may concer-n:-

Be it known that I, CHARLES H. WILLIAMS, of Cleveland, in the county ofCuyahoga and State of Ohio, have invented certain Improvements inOar-Coupling Pins, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawing, and theletters of reference marked there on, making part of this specification,in which- Figure 1 is a Side view of a car-coupling pin made from around bar of iron. Fig. 2 is a side view of a car-coupling pin made from'a hat bar of iron. Fig. 3 is a sectional view of Fig. l. Fig. 4 is asectional view of Fig. 2.

My present invention is a new article of manufacture, and consists indeveloping on a round or flat bar of merchantable iron a solid collar,and leaving an elevation or sufficient stock above said collar for ahandle, and which provides a marketable railroad-carcoupling pin, andone which, for many purposes, is as useful as a nished pin.

The construction and operation of my' invention are as follows: In theaccompanying drawing, A is the pin; B, the Solid collar developedthereon, and which is of uniform dimensions throughout; and G, theelevation or Stock that is left above the collar for a handle. Byreference to my patents of July 15, 1873,

numbered, respectively, 140,980, and 140,981, it will be seen that thispin is produced at the first stage of the process of forming the1inished pin which the system of dies described therein produces 5 or issuch a pin as is made from the round or at bar of Inerchantable ironthrough the action of a single set of dies. The dies with which Ipropose to form this pin are fully described and claimed in my formerpatents, and, therefore, are not referred to here. Nor do I wish tolimit myself necessarily to their use, as the pin itself is a newarticle of manufacture. The pin A may be pointed, as shown at D, throughpressure-dies or any other convenient means.

IVhat I claim as new, and desire to secure by Letters Patent of theUnited States, is

As a new article of manufacture a machinemade car-coupling pin, A,having a solid collar, B, a projection above the same for a handle, andformed from an ordinaryv round or flat bar of nicrchantable iron,substantially as described and shown.

In testimony whereof I have signed my name to this specitication in thepresence of two subscribing witnesses.

CHAS. H. WILLIAMS.
